[Healeys] Testing Voltage Regulator

[Oudesluys]

Analogue instruments may not be as accurate as digital ones but they 
have a hysteresis that damps the movements and stabilizes the readings, 
especially bi-metal ones, that with the easier interpretation by 
position of the hand (it is OK if somewhere near the middle) rather than 
reading the actual figure and interpret what it means makes analogue 
instruments in cars far superior to digital instruments.
